Specification of Letters Patent.

Patented Nov. 24, 1914.

Application fll'ed October 12, 1911. Serial No. 654,362.

To all whom it may concern:

Be it known that I, Jossru Minnie, citizen of the United States, residingat East Hampton, in the'county of Sufl'olk and'state of New York, have invented certain new and useful Improvements in Motors, of which the following is a specification, reference being had therein to the accompanying drawmg.

This invention relates to im roved gas engines and more especially to that type of explosive gas engines known as four cycle engines.

The principal object of this invention is the production of a simple, cheapand du' rable gas engine which may be run at a high rate of speed with certainty and economy.

Another object of this invention is the production of an eflicient gas inlet and outlet control valves.

With these and other objects'in view this invention consists of certain novel constructions, combinations, and arrangements oi parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure l is a side elevation of the engine. Fig. 2 is a vertical section thereof. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a section taken on the line 44 of Fig. 2. Fig. 5 ins front view of the cam mechanism for controlling the valves.

Referring to the drawings by numerals 1 designates the crank casing which is made in two sections, the upper section carryingthe main cylinder 2. The inlet valve cylinder 3 is placed to one side of the main cylinder 2, and the outlet valve cylinder 4 is laced to the other side of said main cyliner 2. A water jacket 5 entirely surrounds the main cylinder and valve cylinders as clearly shown in Fig. 4, thereby forming an efficient cooling means for not only the main cylinder but also for the inlet and exhaust cylinders. vThe inlet cylinder is provided near its outer face with an inlet opening 6 to which is connected the inlet supply pipe 7 through the medium of the bolts 8. The inlet supply pipe 7 is provided with flanges 9 as illustrated in F ig. 2, through which the bolts 8 pass for holding said inlet pipe in engagement with the inlet casing. The

lower end of the.inlet casingii isprovided with a stufling box 10 throu h which asses the inlet valve control to 11 whic rod carries at its' lower end a hook portion 12.

This hook portion carries atits lower ends-- roller 13, which roller engages the cam-1t for controlling the reciprocation-of the valve control rod 11. A collar 15 is carried by the vtions15 and an enlar d end 16 so as to give the inlet valve contro rod 11 the proper reoiprocating motion. Of course, th'e roller 13 a1 owe the can) to act u on the lowerend of the hook portion 12 wit com arativel little friction. A- pin 17 passes tli 11 and a closure nut 18 1 is secured to..the upper section of the crank-casing which is illustrated in Fig. 2. A coil sprin 19 isiin terposed between the pin 17 and ,e-closure (nut 18 for normally holding the rod 11 in its upwardly extended position.

A valve is placed within the-valve casing 3 and said valve comprises an outer eylindrical shell 21 having seated upon the outer face thereofnear each end a pair of packing gaskets 22'for closely fitting against the inner face of the casm 3. A plurality of radial webs 23 exten inwardly from the inner face of the shell 21 and are connected to a collar 24' into which collar is threaded the upper screw-threaded end 25 of thevalve operating rod 11. The upper end of-nthe valve casing 3 is closed by means of a threaded cap 26.

The construction of the valve casing, valve and valve operating mechanism of the ex. haustport is the same as that just described in connection with the inlet port. The cams 14 which operate the inlet and outlet valve control rods 11 are mounted upon shafts 27 which shafts carry upon their outer ends the controlling gears 28 which gears mesh with an operating gear 29 which operatin gear is in turn carried by a shaft 30. wheel 31 is carried by the shaft 30 and to this wheel 31 is connected the rod 32. This rod 32 carries at its forward end a piston 33, which piston works within the main explosion cylinder 2. The inlet valve casing 3 communicates with the ex losion cylinder 2 through the medium of t e inlet port 34 and the outlet or exhaust cylinder 4 communicates with the ex lesion 0 linder 2 through the medium 0 the out st or exhaust port The usual s ark plug 36 is carried by the upper end 0 the cylinder 2 for igniting the compressed char e.

The operation of the device is as folrough tie rod? lower-P e fuel is admitted into the inlet upon bv the exploded gases.

n casing 3 from the pipe 7 throughthe port 6 and as the valve 20 is brought -dovvnvvardly from the position illustrated in Fig.

2 the gases will pass through the valve casing and into the explosion cylinder through the port this time the valve Within the exhaust casing l will rise so as to close the port 35, at the same time the piston 33 rises compressing the uses and upon the explosion of the gases t e piston 33 Will be driven downwardly, thereby rotating the Wheel 81 and the gear 28 through themech- .anism connectin said ear 28 with the b b valve in casing t, said valve will be drawn to the position shown in Fig. 2 to open the exhaust port '35. At the same time, the mechanism connecting gear 28 With the valve in casing 3, Will cause said valve to assume the position shown in Fig. 2 to close port 34. The force of the explosion will cause the piston to return to its upwardly extended position thereby forcing the burnt gases out through the exhaust casing l and through the valve contained therein and upon its return stroke will cause the inlet valve and outlet control valve to again go through the operation just described.

From the above description it will be obvious that a simple and el'iicient device has been produced whereby the inlet and outlet ports will be eilectually controlled so as to prevent any back firing thereby eliminating any chances of setting the carbureter on fire. it will further be obvious that an efficient means has been produced whereby the burnt gases will be readily discharged from the explosion cylinder through the medium 01 the piston 33 returning to its upward stroke after having once been acted course, it

- misses should be understood that the valve 20 Within the casing at is of the same construction as the valve referred to Within the cas ing 3 thereby allowing the gases to readily pass through the valve when the position of the valve is such as to open the passageways.

What ll claim is An internal combustion engine comprising a cylinder provided with oppositely disposed upper fuel inlet and outlet ports, a fuel casing having a base inlet port and an upper outlet port, said upper outlet port communicating with the inlet port of the cylinder, an exhaust casing having an upper inlet'port communicating With said outlet port of the cylinder and a base outlet port, a hollow valve mounted Within said fuel casing for controllingthe outlet port thereof and adapted to permit fuel to enter its base and discharge through the top thereof, a hollow valve in the exhaust casing controlling the inlet port thereof and adapted to permit burnt gases to enter through the top and be discharged through the base thereof, said valves and said fuel casing and exhaust casing having straight Walls throughout their entire length, and said valves adapted to engage said Walls throughout their entire stroke whereby said valves will be held against twisting movement when reciprocating Within said exhaust and fuel casing, a piston in said cylinder, and means for-reciprocating said piston and valves.

In testimony whereof I hereunto afiix my signature in presence of two Witnesses.
